It is recognized that partitioning of the CI among different phases is a key aspect in relation to the field application...

... − ϕ W ) ) Abstract Many production chemicals are complex mixtures of surfactants yet are described by a single partition characteristic such oil soluble or water soluble. This paper presents a simple model of multi-component surfactant mixture partitioning based on the work of Zhu and Free...

... by comparing the control sample to the test samples with the following formula: Based on the results of the extraction testing, the following concentrations were selected to evaluate the effectiveness of the partitioned corrosion inhibitor in solution. Samples were prepared as described above and labeled...

... of corrosion inhibitor (CI) in oil fields requires an understanding of chemical partitioning in the oil and water phases. In this work, the impact of fluid properties and operating conditions on the partitioning behavior of CI has been investigated in the lab. Field oil, synthetic brine, and CI were mixed...

...The oil-water partitioning of CnBDMAC was determined by contacting the required volumes of oil and aqueous phase containing the required concentration of dissolved CnBDMAC within glass cells which were mounted on a magnetic stirrer base within a thermostatted holder. The glass cells (custom built...

... during the venting due to the Joule-Thomson cooling. Abstract When dense phase CO₂ is depressurized and forms a two phase gas/liquid system, impurities will partition between the two phases and go preferentially to the phase where their solubility is highest. Partitioning and depressurization...

... on them to delay or prevent the application of inhibitor treatments. corrosion rate inhibition partitioning INTRODUCTION Inhibition due to the presence of the oil phase was reported in the literature [ 1 - 4 ]. Two mechanisms have to be differentiated here: reducing the corrosion rate due...

... of the inhibitor in a production system. Specifically, the partitioning behavior of corrosion inhibitors is discussed and how this is affected by changes in inhibitor structure, temperature, brine salinity and oil type. Competitive, parasitic adsorption onto unwanted surfaces is discussed. The affinity of various...

Table 2 provides representative partitioning data for the FA Am Salt active between kerosene and brine at initial concentrations...

... products gave acceptable inhibition performance and the performance ranking among these products also varied significantly in brines with or without 20% hydrocarbon. This indicates that partitioning characteristics of these products are different. Environmentally friendly corrosion inhibitors CO2...

...Abstract A new strategy has been applied successfully to pre-select corrosion inhibitors and short-list products to be considered by the operators. In particular the more comprehensive evaluation of the partitioning properties of the chemicals has improved the chances of successful application...

...Corrosion inhibitor selection for this type of application is complicated by a number of factors: The phase composition of the fluids in the line can vary significantly from the wellhead to the receiving platform. This has implications for the partitioning of the inhibitor and its components...
